If you look at the present Chevrolet line-up, it only has one van to offer. That model is the Express van, and there hasn't been an all-new model since 1996. The 27-year-old van even got a new engine for the 2020 model year, but it soldiers on as the only one of its kind to wear a Chevrolet badge.
But back then, Chevy had more vans available, namely the Venture and the Astro. The Venture was killed off in 2004 and replaced by the Uplander (discontinued in 2009). The Astro, on the other hand, hung around for another year. The 'midi-van' (as General Motors called it) wrapped up 20 years of production in 2005.
